LCA Engineering study plan

Distinguish the four ISO 14040/14044 phases and state, from memory, which phase each of ten given activities belongs to (e.g. allocation, boundary setting, normalisation, critical review).

Write a one-page goal-and-scope statement for a product you know well, naming intended application, audience, functional unit, reference flow and system boundary.

Define functional units for three competing systems (e.g. 1 m² of wall insulation over 50 years, 1 000 L of delivered drinking water) and justify the declared reference flow for each.

Explain in writing when a comparative assertion triggers a critical review requirement and when ISO 14044 requires a panel versus a single reviewer.

Build a process flow diagram for your case study that maps every unit process from raw-material extraction to end-of-life, and label each input and output as product, co-product, waste or emission.

Apply the ISO 14044 allocation hierarchy to at least two multi-output processes in your case study, documenting whether you used subdivision, system expansion, physical or economic allocation and why.

Calculate allocation factors for one co-product process under both mass and economic bases, and quantify how much the main product's inventory changes between the two.

Assemble a data-collection sheet with fields for quantity, unit, geography, technology, reference year and source, and populate it with at least 15 foreground data points.

Model the case-study product in LCA software using at least two background databases, and export a process-level inventory contribution table.

Audit five dataset records against the data-quality dimensions of ISO 14044 (time, geography, technology, precision, completeness) and record a pass/fail judgement for each.

Document your database version, software version and dataset names so the model could be rebuilt by another analyst.

Reconcile a hand calculation of one unit process against the software result and explain any discrepancy above 2%.

Classify ten inventory flows into the correct midpoint impact categories and name the characterisation model behind each (e.g. IPCC AR6 for climate change, ReCiPe or USEtox for toxicity).

Compute a characterisation result by hand for one category using given characterisation factors, and verify it against the software output.

Compare two LCIA methods on the same model and explain the differences in category coverage, characterisation models and units.

Distinguish midpoint from endpoint indicators and state one decision-context reason for choosing each.

Run a one-at-a-time sensitivity analysis on the five most influential parameters and rank them by effect on the climate-change result.

Perform a scenario analysis on at least two modelling choices (e.g. allocation method, end-of-life scenario, electricity mix) and report the spread in results.

List the main uncertainty sources in your model, label each as parameter, scenario or model uncertainty, and state which can be quantified with the data you have.

Write completeness and consistency checks against your original goal and scope, and flag any requirement you failed to meet.

Draft the interpretation chapter of an LCA report following ISO 14044 structure: identification of significant issues, evaluation, and conclusions with limitations.

Prepare a critical-review response plan: list the documents a reviewer needs, the review type required for your intended application, and how you would answer three likely reviewer challenges.

Define and apply data-quality indicators (e.g. pedigree matrix scores) to your foreground data and state the resulting uncertainty range you will carry forward.

Produce a reproducibility check by having a colleague or yourself rebuild one subsystem from your documentation alone.

Map the requirements of ISO 14067 for a product carbon footprint onto your case-study model and list the extra clauses beyond ISO 14044 (e.g. fossil and biogenic carbon reporting, land-use change, removals).

Separate and report fossil, biogenic and land-use-change emissions for your case study, and state how each is treated in the chosen method.

Identify the required content of an EPD under ISO 14025 and the relevant PCR, and check your model against that PCR's declared-unit and parameter rules.

Explain the difference between a self-declared claim, a third-party verified EPD and a Type I label, and state what verification each requires.

Apply circular-economy indicators (e.g. recycled content, recyclability, material circularity) to your case study and state their limits compared with the LCA result.

Generate three eco-design options from your hotspot analysis and screen each for burden shifting across at least three impact categories.

Outline how a life cycle sustainability assessment would extend your model to social and economic dimensions, naming one method or framework for each.

Complete two timed mixed-domain practice sets and review every wrong answer back to the governing ISO clause or method rule.
